Chemical alumina (also called non-metallurgical alumina ) ,according to its chemical composition, crystal structure, particle size, purity, hardness, sintering degree, and so on, there are about 300 varieties, its application field is permeated into the advanced material industry in all fields.And pseudo boehmite, as important part of the many varieties of alumina, due to the high specific surface area, wide range of entrance (large, medium and small hole), molding and sol thixotropic performance good features, such as in the petrochemical industry, widely used in molecular sieve desiccant, adsorbent, ceramic molding adhesive, molding adhesive, preparation of activated alumina catalyst carrier and raw materials, etc.
ZIBO TONYEAR produces very good pseudo-boehmite, including low sodium, high viscosity, mesoporous, macroporous products in the petroleum catalyst, blue corundum, adhesives and other industries are very popular.
Process route of pseudo-boehmite: alcohol-aluminum hydrolysis or neutralization production of pseudo-boehmite main process route design, there are two kinds of alcohol-aluminum hydrolysis method and neutralization method.ZIBO TONYEAR adopts a green carbonization process (a kind of neutralization method) to prepare pseudo-boehmite.
Firstly, let’s look at the process of alcohol aluminum hydrolysis. The pseudo-boehmite prepared by this method has the characteristics of high specific surface area, high purity and concentrated pore size distribution.Alcohol aluminum hydrolysis process of quasi thin diaspore says SB powder preparation, has only a few countries have production in the world, the typical products are Germany Sasol PURAL_SB powder production, the SB has good crystal shape, pore structure is easy to control and high specific surface area and purity characteristics, is widely used in catalytic fields (other areas it is difficult to digest, presumably so expensive raw materials), (but) like Germany alcohol aluminum method to process the production cost is higher, and some problems such as environmental pollution and high energy consumption, even if can master the core technology, want to industrialized production, the existing laws and regulations is not possible to support of our government.
The second mainstream process is the neutralization method (including the acid method and the alkali method), which is a process method for preparing pseudo-boehmite after aluminum salt or aluminic acid salt solution in the process of acid-base neutralization. It has the characteristics of easy access to raw materials and low cost.Among the many neutralization molding routes, carbonization (one of the alkaline methods, which USES the reaction of carbon dioxide and sodium alloyate to prepare alumina) is a relatively young and promising process for preparing pseudo-boehmite.Prepared by carbonization method is characterized by green environmental protection and low cost. It can be used as a low-cost substitute for SB powder, which is conducive to reducing the purchase cost of application enterprises.Green environmental protection process is the mainstream of industrial development at present. ZIBO TONYEAR adheres to the development trend, practices the policy of sustainable development in a down-to-earth way, and rapidly realizes the industrialization of carbonization. Through continuous innovation and steady development, ZIBO TONYEAR has built a leading and internationally advanced r&d and preparation base in China.ZIBO TONYEAR has powerful equipment technology and advanced production technology, the production line is highly informationized, intelligent and automated, and the product quality is stable, the specification is complete and the consistency is good.At present, ZIBO TONYEAR can produce personalized products for users according to their application needs.By controlling the process parameters of carbonization preparation, various brands of pseudo-boehmite ,alumina microspheres can be produced on demand, among which 6006 products are pseudo-boehmite with high viscosity, the dry products are in powder form, and the wet products are in white colloid form (the water state is thixotropic gel).The product is non-toxic, odorless, high crystal phase purity, good gel solubility, has very high adhesion, higher than the surface, moderate pore volume, good dispersion.
At present, 6006 series pseuod boehmite is widely used in the production of catalyst carrier, catalyst and adsorbent.6006 series products although than SB powder with high purity, but with as low cost alternative to SB catalyst use (no problem) can meet the demand of users, and the quality is stable, the product industry has gone through a third party authority of qualification test, user authentication using contrast widely recognized, such as sinopec, domestic large customers, and catalyst of companies such as the United States, the European Union and Japan, South Korea, India and other companies purchasing application, used as a catalyst for production of binder, the production of SAPO molecular sieve series, such as aluminum source use.
ZIBO TONYEAR’s customers are mainly distributed in China, Russia and South Korea.Aim at the forefront of the industry: like most enterprises, ZIBO TONYEAR focuses on the market demand for “special molecular sieves and catalysts” and other products. While maintaining the traditional industry, ZIBO TONYEAR also pays close attention to the market demand and develops promising and potential new projects. Special molecular sieves and catalysts are currently the major products in demand from the industry.Petroleum catalyst carrier and catalyst are indispensable key materials in petroleum smelting industry, and molecular sieve is the most widely used catalytic material in oil refining and petrochemical industry.China’s petroleum catalyst carrier is currently mainly dependent on imports, many foreign oil majors want to seek more affordable Chinese products.Under this opportunity, ZIBO TONYEAR aimed at the market demand of the industry and set up production lines of “special molecular sieve and catalyst” and other products.
In addition to having its own core technology r&d team and new product development research group, ZIBO TONYEAR has also established long-term cooperative relations with university scientific research institutions such as institute of materials, Chinese academy of sciences, xiamen university, changsha university of science and technology, and Beijing university of chemical technology, as well as well-known molecular sieve product laboratories and experts at home and abroad.At the same time, we also set up graduate practice bases and product application bases with 3 colleges and universities.In addition to its strong soft power, ZIBO TONYEAR’s hard power is not to be underestimated. At present, ZIBO TONYEAR has modern standard factory building of 25,000 square meters, synthetic reaction device, advanced catalyst production and test equipment.ZIBO TONYEAR product analysis and testing center has perfect detection mechanism and various advanced detection databases, equipped with globally advanced detection means, including but not limited to technologically advanced laser particle size meter, visible spectrophotometer and other equipment.Below is the scene of the real shot, you can see.
